# Multi Debrid Downloader
|
|
|
|
Desktop downloader with fast queue management, automatic extraction, and robust error handling.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
## Why this tool?
|
|
|
|
- Familiar download-manager workflow: collect links, start, pause, resume, and finish cleanly.
|
|
- Multiple debrid providers in one app, including automatic fallback.
|
|
- Built for stability with large queues: session persistence, reconnect handling, resume support, and integrity verification.
|
|
|
|
## Core features
|
|
|
|
### Queue and download engine
|
|
|
|
- Package-based queue with file status, progress, ETA, speed, and retry counters.
|
|
- Start, pause, stop, and cancel for both single items and full packages.
|
|
- Multi-select via Ctrl+Click for batch operations on packages and items.
|
|
- Duplicate handling when adding links: keep, skip, or overwrite.
|
|
- Session recovery after restart, including optional auto-resume.
|
|
- Circuit breaker with escalating backoff cooldowns to handle provider outages gracefully.
|
|
|
|
### Debrid and link handling
|
|
|
|
- Supported providers: `realdebrid`, `megadebrid`, `bestdebrid`, `alldebrid`.
|
|
- Configurable provider order: primary + secondary + tertiary.
|
|
- Optional automatic fallback to alternative providers on failures.
|
|
- `.dlc` import via file picker and drag-and-drop.
|
|
|
|
### Extraction, cleanup, and quality
|
|
|
|
- JVM-based extraction backend using SevenZipJBinding + Zip4j (supports RAR, 7z, ZIP, and more).
|
|
- Automatic fallback to legacy UnRAR/7z CLI tools when JVM is unavailable.
|
|
- Auto-extract with separate target directory and conflict strategies.
|
|
- Hybrid extraction: simultaneous downloading and extracting with smart I/O priority throttling.
|
|
- Nested extraction: archives within archives are automatically extracted (one level deep).
|
|
- Pre-extraction disk space validation to prevent incomplete extracts.
|
|
- Right-click "Extract now" on any package with at least one completed item.
|
|
- Post-download integrity checks (`CRC32`, `MD5`, `SHA1`) with auto-retry on failures.
|
|
- Completed-item cleanup policy: `never`, `immediate`, `on_start`, `package_done`.
|
|
- Optional removal of link artifacts and sample files after extraction.
|
|
|
|
### Auto-rename
|
|
|
|
- Automatic renaming of extracted files based on series/episode patterns.
|
|
- Multi-episode token parsing for batch renames.
|
|
|
|
### UI and progress
|
|
|
|
- Visual progress bars with percentage overlay for packages and individual items.
|
|
- Real-time bandwidth chart showing current download speeds.
|
|
- Persistent download counters: all-time totals and per-session statistics.
|
|
- Download history for completed packages.
|
|
- Vertical sidebar with organized settings tabs.
|
|
- Hoster display showing both the original source and the debrid provider used.
|
|
|
|
### Convenience and automation
|
|
|
|
- Clipboard watcher for automatic link detection.
|
|
- Minimize-to-tray with tray menu controls.
|
|
- Speed limits globally or per download.
|
|
- Bandwidth schedules for time-based speed profiles.
|
|
- Built-in auto-updater via `git.24-music.de` Releases.
|
|
- Long path support (>260 characters) on Windows.
|
|
|
|
## Installation
|
|
|
|
### Option A: prebuilt releases (recommended)
|
|
|
|
1. Download a release from the `git.24-music.de` Releases page.
|
|
2. Run the installer or portable build.
|
|
3. Add your debrid tokens in Settings.
|
|
|
|
Releases: `https://git.24-music.de/Administrator/real-debrid-downloader/releases`
|
|
|
|
### Option B: build from source
|
|
|
|
Requirements:
|
|
|
|
- Node.js `20+` (recommended `22+`)
|
|
- npm
|
|
- Windows `10/11` (for packaging and regular desktop use)
|
|
- Java Runtime `8+` (for SevenZipJBinding sidecar backend)
|
|
- Optional fallback: 7-Zip/UnRAR if you force legacy extraction mode
|
|
|
|
```bash
|
|
npm install
|
|
npm run dev
|
|
```
|
|
|
|
## NPM scripts
|
|
|
|
| Command | Description |
|
|
| --- | --- |
|
|
| `npm run dev` | Starts main process, renderer, and Electron in dev mode |
|
|
| `npm run build` | Builds main and renderer bundles |
|
|
| `npm run start` | Starts the app locally in production mode |
|
|
| `npm test` | Runs Vitest unit tests |
|
|
| `npm run self-check` | Runs integrated end-to-end self-checks |
|
|
| `npm run release:win` | Creates Windows installer and portable build |
|
|
| `npm run release:gitea -- <version> [notes]` | One-command version bump + build + tag + release upload to `git.24-music.de` |
|
|
| `npm run release:codeberg -- <version> [notes]` | Legacy path for old Codeberg workflow |
|
|
|
|
### One-command git.24-music release
|
|
|
|
```bash
|
|
npm run release:gitea -- 1.6.31 "- Maintenance update"
|
|
```
|
|
|
|
This command will:
|
|
|
|
1. Bump `package.json` version.
|
|
2. Build setup/portable artifacts (`npm run release:win`).
|
|
3. Commit and push `main` to your `git.24-music.de` remote.
|
|
4. Create and push tag `v<version>`.
|
|
5. Create/update the Gitea release and upload required assets.
|
|
|
|
Required once before release:
|
|
|
|
```bash
|
|
git remote add gitea https://git.24-music.de/<user>/<repo>.git
|
|
```
|
|
|
|
PowerShell token setup:
|
|
|
|
```powershell
|
|
$env:GITEA_TOKEN="<dein-token>"
|
|
```
|
|
|
|
## Typical workflow
|
|
|
|
1. Add provider tokens in Settings.
|
|
2. Paste/import links or `.dlc` containers.
|
|
3. Optionally set package names, target folders, extraction, and cleanup rules.
|
|
4. Start the queue and monitor progress in the Downloads tab.
|
|
5. Review integrity results and summary after completion.
|
|
|
|
## Project structure
|
|
|
|
- `src/main` - Electron main process, queue/download/provider logic
|
|
- `src/preload` - secure IPC bridge between main and renderer
|
|
- `src/renderer` - React UI
|
|
- `src/shared` - shared types and IPC contracts
|
|
- `tests` - unit tests and self-check tests
|
|
- `resources/extractor-jvm` - SevenZipJBinding + Zip4j sidecar JAR and native libraries
|
|
|
|
## Data and logs
|
|
|
|
The app stores runtime files in Electron's `userData` directory, including:
|
|
|
|
- `rd_downloader_config.json`
|
|
- `rd_session_state.json`
|
|
- `rd_downloader.log`
|
|
|
|
## Troubleshooting
|
|
|
|
- Download does not start: verify token and selected provider in Settings.
|
|
- Extraction fails: check archive passwords, JVM runtime (`resources/extractor-jvm`), or force legacy mode with `RD_EXTRACT_BACKEND=legacy`.
|
|
- Very slow downloads: check active speed limit and bandwidth schedules.
|
|
- Unexpected interruptions: enable reconnect and fallback providers.
|
|
- Stalled downloads: the app auto-detects stalls within 10 seconds and retries automatically.

## Changelog
|
|
|
|
Release history is available on [git.24-music.de Releases](https://git.24-music.de/Administrator/real-debrid-downloader/releases).
|
|
|
|
### v1.6.58 (2026-03-05)
|
|
|
|
- Fixed extraction progress oscillation (`1% -> 100% -> 1%` loops) during password retries.
|
|
- Kept strict archive completion logic, but normalized in-progress archive percent to avoid false visual done states before real completion.
|
|
|
|
### v1.6.57 (2026-03-05)
|
|
|
|
- Fixed extraction flow so archives are marked done only on real completion, not on temporary `100%` progress spikes.
|
|
- Improved password handling: after the first successful archive, the discovered password is prioritized for subsequent archives.
|
|
- Fixed progress parsing for password retries (reset/restart handling), reducing visible and real gaps between archive extractions.
